Frogs can and often do bring disease into garden ponds by moving from
infected places. Red Leg is a serious and common disease of frogs that
is transmitted to fish causing serious problems. Every spring I treat
my pond with a suitable anti-parasite/bacteria and the fish (and
arriving frogs) stay healthy.

We did find a fish with a fungal disease earlier this year - we removed
it, treated it but it died. I then treated the pond with FC+.

I also bought a water testing kit - I'll test the pond later today.

ph 7.5 Ok
Nitrite 0 ppm Ok
O2 13-15 ppm Ok
Ammonia 0 ppm Ok
Chlorine/Chloramine 0 ppm Ok

BUT Chlorine/Chloramine in tap water 0.3 ppm and we have been refilling
the pond from the tap which I guess may have been stressing the fish -
the rain-water barrels have just found another use.

If you run out of rainwater, don't panic, get some tap water
conditioner/dechlorinator ie. Tap Safe by Tetra (one I use) not only does it
remove chlorine/Chloramine, but removes heavy metals from tap water which
are also damaging to fish, however, you should be aware that rainwater is
likely to be somewhere in the region of ph 5-6 which is acidic and goldfish
require alkaline water of 7-7.5. If you test your rainwater and find it's
too acidic you can put crushed oystershell in your filter which will bring
your ph up. There are also other things like Arm & Hammer baking soda which,
if you add that to the water the max ph it will reach is 8.2 (normally sits
around 7.9) however you have to be careful not to raise the ph by more than
..2 per day as this may lead to ph shock and kill the fish, so it needs to be
done very slowly.

We have a small pond and there are many tadpoles. I bought a dozen small goldfish today and once acclimated we put them in the water. The water is very clear and my children and I watched in shock as several tadpoles attached themselves to the goldfish and literally weighed the goldfish down where they couldn’t even swim away. My little boys put their hands in the water to get the tadpoles off the fish. We watched for over an hour as these tadpoles kept attaching (biting) the goldfish. We went in the house for an hour and when we came back there we’re 2 fish dead with scales missing off the sides and bellies The tadpoles we’re feeding on them. These poor fish. I had no idea this would happen And wouldn’t have believed it if I had not seen it with my own eyes. These tadpoles are aggressive and they are much smaller than the fish. Probably 20 tadpoles to 1 fish.l in size. So yes tadpoles have the potential to eat and kill other fish in your pond, especially if 10-20 attach to an even larger fish.

I am having the same problem. This year I seem have thousands more tadpoles than usual and cannot see the fish without a dozen or so tadpoles swimming after them. They are attaching to fish and eating their dorsal fins and the scales off their backs. The fish now have bare patches and no dorsal fins, just bones sticking up. It is definitely the tadpoles causing this due to there being so many of them and not enough food. I have removed three bucket fulls of tadpoles from the pond and now make sure that there is always plenty of fish food around the plants to keep the remaining tadpoles happy. The fish damage has now stopped but, of course, the bare patches are starting to get fungal growths. I have dosed the pond with Medifin and keeping watch. Next year we will remove the frogspawn to a local pond and just keep the newts and toads.
